driven only when the bobbins are to operate and wherein the gaps in the drivers are so formed that arrested drivers coactto guide the bobbins at the crossing-points in the track. In such a construction a specially small pitch between centers of drivers, namely that of 30-35 mm., is possible.

An embodiment of the present invention is illustrated by way of example in the accompanying drawings wherein,

Fig. l is a diagrammatic side elevation of the new braiding machines with their essential parts shown diagrammatically,

Fig. 2 a front elevation of a group of four braiding machines with common operating machinery,

Fig. 3 a vertical section of a portion of the track of the braiding machine, shown in about actual size, and

Fig. i a plan view of a portion of the track.

Referring to the drawings, in the example shown the common machine-frame comprises a number of columns 1 extending down to the floor and intermediate columns 2 which are connected together by longitudinal bars 3 and at their upper ends carry the base-plates e of the several braiding machines. Each of those b aiding machines is provided in the usual manner with a top plate 6 serving for guidance of the conventionally illustrated bobbins and is furnished with a suitable jacquard gear 7, draw-off rolls 8 and reeling device 9. The driving means comprise a counter-shaft 11 journalled below the f 'ame and driven through a pair of gear-wheels 12 by an electromotor 13, and connected by separate belt-drives 1st with the four individual braiding machines. Behind each of these belt-drives 1% is provided in known manner a disengageable coupling, not shown, whereby each of the several braiding machines may be individually thrown into and out of action.

The construction of the individual braiding machines, as is specially clear from Figs. 3 and at, may be conveniently so chosen in known manner that the plates 15 mounted at the level of the top plate 6 serve simultaneously as drivers and are provided with gaps for receiving and guiding the bobbins. Drivingis effected. likewise in known man ner. by a gear wheel 17 running continuously on the fixed column, the upper edge of which wheel is provided with a clutch face 18 for engagement with a movable clutch member 1.). This movable clutch member 19 is slidable on a sleeve 20 of the plate 15 coupled to turn with said half-coupling and obtains its sliding moven'ient from a fork 2%; controlled by the jacquard rod-connections 21, 22 and the spring 23. Said fork when at the level shown, that is, in the uncoupled position, engages by means of its lug 25 in a groove 26 in the lower side of the plate 15 and thereby secures the driven plate and with it the bobbin in their normally inactive positions, i. e., positimis of rest.

As seen from Figs. 3 and d: which show actual size, the bobbin 5 and coil 30 thereon are substantially smaller than hitherto used in braiding machines and to just the same extent are the remaining dimensions of the machine made correspondingly smaller, so that the pitch, that is, the distance between two adjacent plates amounts in the particular machine disclosed, to only 32 min, as Fi 4 shows.

ince owing to the plates being made smaller, the pitch-circle diameter, that is, the circle whereon the entire row of plates is arranged, is correspondingly smaller, that angle at the centre of the machine which is formed by adjacent threads from the bobbins remains the same and an always accurate action of the heaters for driving up and firmly holding the tln'ead-crossings is ensured. On the other hand, owing to this reduction in dimensions, the track of the bobbins is substantially shortened and the centrifugal and accelerating forces are reduced, so that a considerably higher speed of the machine is possible and easy and quiet running is guaranteed.

Obviously, the invention is not limited to the embodiment shown, but other embodiments of the invention are possible, in particular, there might be arranged on a common machine-frame, instead of four of the individual machines, more or less than this number if desired.

What I claim is 1. The combination, in a single-thread braiding machine, of a raceway plate, and a group of raceway carriers on the raceway plate, said carriers having a pitch less than 50 mm. from center to center of adjacent carriers throughout the group.

2. The combination, in a single-thread braiding machine, of a raceway plate, and a group of raceway carriers on the raceway plate, said carriers having a pitch of suhstantially 30 to mm. from center to center of adjacent carriers throughout the group.

3. The combination, in a single-thread braiding machine, of a raceway plate, and a group of disk-shaped raceway carriers on the raceway plate, each having a pair of diametrically disposed peripheral driving recesses, said carrier disks having a pitch less than mm. from center to center of adjacent carriers throughout the group.

4. The combination, in a single-thrczul braiding machine, of a raceway plate, and a group of disk-shaped raceway carriers on the raceway plate, each having a pair of diametrically disposed peripheral driving recesses, said carrier disks having a pitch of group. 4

5'.jIn a multi-braiding machine structure, a frame, a plurality of single-thread braiding machines mounted. onsaidframe, each machine including a raceway plate and a group of carriers mounted thereon, thecarceeding 35 mm.',

riers ofea'ch machine having a pitch from I a center to center of adjacent carriers not exa-single-driving means; and a separate jacquard drive mechanism for each machine actuated by said driving means. a
